SBR - Styrene Butadiene Rubber

This is one of the highest used general purpose synthetic elastomers. It has properties similar to NR, generally weaker except in abrasion and a slightly high upper temperature limit. It is found extensively in the tire industry along with footwear and flooring.

Good mechanical properties
Excellent abrasion resistance
Wide temperature range from below -40°C/-40°F to +100°C/212°F

ASTM D2000 “AA/BA” type
Mil/AMS-R-6855 Class 3 & 5
